2008 Toyota SIENNA problems and owner complaints

UNINTENDED ACCELERATION INCIDENT. CAR WAS DRIVEN 200 MILES THE PREVIOUS NIGHT AND GARAGED. THE NEXT MORNING, CAR WAS STARTED, BACKED OUT OF DRIVEWAY, AND DRIVEN 15 MPH FOR 1/4 MILE UNTIL ON MAIN ROAD. AFTER TRAVELING 0.4 MILES ON MAIN ROAD I SLOWED TO A RED LIGHT. THE ENGINE STARTED RACING (BUT NOT RED-LINING). I AM ABSOLUTELY SURE MY FOOT WAS NOT ON THE ACCELERATOR PEDAL. I SHIFTED INTO NEUTRAL, WHICH REMOVED THE FORWARD PRESSURE, AND AFTER A SECOND OR TWO, THE RPMS DRIFTED BACK INTO THE NORMAL RANGE. THIS IS THE MOST RECENT OCCURRENCE. OTH…

PROBLEM OCCURS AFTER SLOWING DOWN AT A STOP SIGN OR INTERSECTION AT THE SPEED BETWEEN 5 TO 10 MPH AND THEN GO TO INCREASE SPEED. THE TRANSMISSION HESITATES. ONE TIME THE ENGINE SEEMED TO ROAR UP, BUT THE CAR DIDN'T MOVE.... THIS HESITATION OCCURS WHEN TRANSMISSION IS SHIFTING AT LOW SPEEDS WHEN ACCELERATING AFTER SLOWING DOWN AT AN INTERSECTION OR TURNING AT A CORNER. THIS OCCURS INTERMITTENTLY BUT IS QUITE NOTICEABLE. I CAN OFTEN REPRODUCE HESITATION WITH A HARD BRAKE FOLLOWED BY HEAVY THROTTLE. *TR

I ACCIDENTALLY HIT THE CRUISE CONTROL IN MY 2008 TOYOTA SIENNA WHEN THE CONTROL LEVER WAS OVER THE WINDSHIELD WIPER CONTROL IN A SLIGHT LEFT TURN, RESULTING IN THE CRUISE CONTROL GOING UNEXPECTEDLY INTO "RESUME". BECAUSE OF INCLEMENT WEATHER I HAD SLOWED DOWN AND WAS NOT EXPECTING THE INSTANT ACCELERATION. TOOK A COUPLE SECONDS TO REALIZE WHAT HAD HAPPENED WHEN I HAD TRIED TO OPERATE THE WINDSHIELD WIPER CONTROL. THE TOYOTA CRUISE CONTROL LEVER MOUNTED ON THE STEERING COLUMN WHERE IT TURNS WITH THE WHEEL APPEARS TO BE A LESS THAN DESIRABLE E…

TL* THE CONTACT OWNS A 2008 TOYOTA SIENNA. WHILE DRIVING APPROXIMATELY 65 MPH, THE ENGINE STALLED WITH THE ILLUMINATION OF THE ENTIRE INSTRUMENT PANEL.

THE ENGINE RESTARTED EACH TIME THE FAILURE OCCURRED AND THE VEHICLE WAS TAKEN TO A DIFFERENT DEALER WHO COULD NOT LOCATE A PROBLEM. THE CONTACT PLANNED TO TAKE THE VEHICLE FOR A THIRD OPINION TO POSSIBL…

AT HIGHWAY SPEED, ALL LIGHTS FLICKER ON THEN LOST ALL POWER.......OILLINE HAD LEAKED ON ALTERNATOR BELT CAUSING LOSS OF POWER. LUCKILY POWER LOSS PREVENTED ENGINE DAMAGE FROM OIL LEAK. WE HAD NOT BEEN NOTIFIED BY TOYOTA ABOUT THE OIL LINE PROBLEM OR RECALL.....ONLY AFTER A LOCAL GARAGE FIXED THE LINE DID I FIND OUT ABOUT THE RECALL....I WOULD HAD IT REPLACED EARLIER IF I HAD BEEN NOTIFIED. *TR

TO CHANGE A TIRE THE FLOOR JACK WAS PLACED IN FRONT OF THE LEFT REAR TIRE A LITTLE TOO FAR TOWARD THE CENTER (FROM LEFT TO RIGHT) OF THE VEHICLE. THE PLACEMENT APPEARED TO BE AGAINST STEEL BUT IN REALITY THE MATERIAL WAS BLACK PLASTIC. WHEN THE VEHICLE WAS LIFTED THE PLASTIC GAVE WAY AND DAMAGED THE FILLER PIPE TO THE FUEL TANK CAUSING FUEL TO BE DUMPED TO THE STATION DRIVE DURING THE REFUELING PROCESS. IT WOULD APPEAR THAT THE PLASTIC IS THERE TO PROTECT THE FUEL FILLER PIPE. THIS WOULD OCCUR EACH TIME REFUELING TAKES PLACE. THE CONSEQUENC…
